3. What is the effect on the equilibrium concentration of each substance in the system (increase, decrease, an initial increase followed by a slight decrease, or no change) when the listed reagents are added? a) H2(g) is added to the system described by: C₂H6(g) → H2(g) + C₂H4(g) b) CuSO4(s) is added to the system described by: Cu²+ (aq) + 4NH3(aq) Cu(NH3)4²+ (aq) NOTE: Assume that CuSO4(s) will completely dissolve in the aqueous solution of NH3 or NH3(aq). 4. What is the effect of an increase in pressure on each of the following equilibrium systems? Briefly explain your reasoning using the word shift. a) C₂H6(g) → H2(g) + C₂H4(g) b) CO(g) + ¹½O2(g) →→ CO2(g) + heat 2+ c) Cu²+ (aq) + 4NH3(aq) Cu(NH3)4²+ (aq) d) PbSO4(s) + H+ (aq) Pb²+ (aq) + HSO4 (aq)
